3.Installation

Note:The unit should only be installed in the dry interior rooms. Please separate

routing of sensor wires and mains wires. Make sure the controller as well as the system are

not exposed to the strong electromagnetic fields.

3.1 Mounting controller

Follow the below steps to mount the controller on the wall.

 Unscrew the crosshead screw from the cover and

remove it along with the cover from the housing.

 Mark the upper fastening point on the wall. Drill and

fasten the enclosed wall plug and screw leaving the

head protruding.

 Hang the housing from the upper fastening point and

mark the lower fastening points (centers 180 mm).

 Drill and insert lower wall plugs.

 Fasten the housing to the wall with the lower fastening

screw and tighten.

 Carry out the electrical wiring in accordance with the terminal allocation

 Put the cover on the housing. Attach with the fastening screw.

3.2 Wiring connection

According to the way of installation, wire can be connected from hole A on the bottom plate or

from hole B, using a suitable tool (like knife) to cut the plastic of A.

Note: wires must be fastened by fixing clamps on position C.

 Advice regarding the installation of temperature sensors:

① Only original factory equipped Pt1000 temperature sensors are approved for using with

the collector, it is equipped with 1.5m silicon cable and suitable for all weather conditions,

the cable is temperature resistant up to 280oC, connect the temperature sensors to the

corresponding terminals with either polarity.

② Only original factory equipped NTC10K,B=3950 temperature sensors are approved for

Operation manual of solar controller SR658

Page 10 of 113

using with tank and pipe, it is equipped with 3m PVC cable, and the cable is temperature

resistant up to 105

o

C, connect the temperature sensors to the corresponding terminals

with either polarity.

③ All sensor cables carry low voltage, and to avoid inductive effects, must not be laid close

to 230 Volt or 400 Volt cables (minimum separation of 100mm).

④ If external inductive effects are existed, e.g. from heavy current cables, overhead train

cables, transformer substations, radio and television devices, amateur radio stations,

microwave devices etc., then the cables to the sensors must be adequately shielded.

⑤ Sensor cables may be extended to a maximum length of ca. 100 meter, when cable’s

length is up to 50m, and then 0.75mm

2

cable should be used. When cable’s length is up

to 100m, and then 1.5mm

cables should be used.

Page 12 of 113

 Connecting the signal wire from the high-efficiency pump

Signal wire 1 from the high-efficiency pump is connected to GND port of controller

Signal wire 2 from the high-efficiency pump is connected to PWM1 port of controller

Signalwire3 from the high-efficiency pump is signal wire FB1, it is not connected to FB1 port of

controller

Some pumps connections are available as above, for example:

Wilo Yonos PARA ST15/7.0 PWM2 M

Note:

 High-efficiency pump with 0-10V signal only has 2 signal wires, connected to the

corresponding port GND, PWM1 (PWM2 or PWM3) of controller.

 Blue wire not always represent for “GND” and brown wire not always represent for

“PWM”.

”PWM” from pump must be match for “PWM” from controller.

”GND”from pump must be match for “GND” from controller.

3.4 TF (MicroSD) Card

 Controller is equipped with a slot for TF (Micro SD) card.

 With TF (MicroSD) card, following functions can be carried out

 Save the measurement value and parameters value onto the MicroSD TFcard. After
